Specification of Letters Patent.

latented Dec. 4, 1906.

Application filed March 19, 1906-. Serial No. 306,900.

To all whom it N l/(Ly concern;

Be it known that we, THOMAS Enoon Cox and WILLIAM LENOX Cox, citizens ofthe United States, residing at Birmingham, in the county of Jeffersonand State of Alabama, have invented certain new and useful Improvementsin Draft Appliances, of which the following is a specification.

Our invention relates to draw-bars and draw-heads, and has for itsobject to provide a draw-bar embodying new and improved means forattachment to the frame of :a car and new and improved means for takingup the movement of the draw-bar under stress of draft or buffing.

A further object of the'in'vention is to provide a draw-bar embodyingnew and improved features of convenience, strength, safety, andefiiciency.

With these and other objects in view the invention comprises certainother novel constructions and arrangements of parts, as will behereinafter fully described and claimed.

In the drawings, Figure 1 is an inverted plan view of the improvedcoupler. Fig. 2 is a top plan view of the coupler the carfloor removed.Fig. 3 is a longitudinal sectional view of the coupler, taken on line 33 of Figs.1and2.

Like characters of reference designate corresponding parts throughoutthe several views.

In its preferred embodiment the improved draw-bar forming thesubject-matter of this application is mounted beneath. the usual andordinary lls, as 10, of a car by securing transversely of the side sillsthe cross-bar 11, to the forward side of which is rigidly secured aguide member 12. Adjacent the endof the car to which the draw-head isapplied are mounted brackets 13 and 13, spaced apart sufficiently topermit the draw-bar 14 to move longitudinally therebetween, the saiddraw-bar extending beyond the end of the car and provided with'adraw-head having shoulders 15 and '16 extending laterally therefrom.Upon the brackets 13 and 13 adjacent their rearward ends is secured astirru 17, pro ortion'ed to embrace the drawar 14 an to support itbetween the said brackets.

"secured together at their forward ends by means of a rod 18 extendingtherethrough transversely of the car and provided be- The brackets 13and 13 are tween the said brackets with a sleeve or roller 19, uponwhich the draw-bar rests and is movable.

The draw-bar 14 at the point where it extends through the guide 12 isreduced in size and is preferably formed circular in cross' section, asat 20, defining a shoulder 21, between which and the guide 12 isdisposed a coil-spring 22. Adj acent the ends of the bar 20 and withinthe guide 12 is" disposed a washer 23 in any approved manner, as by apin 24, and'betweenthe said'washer and the guide 12 is disposed a spring25.

Upon the upper surface of the draw-bar 14 is formed or secured a lug orbracket 26, rigid with the bar, having therein mounted a bolt 27,provided at its forward end with a rigidly secured to the beam of; thecar, and betweenthe said plate'29 and the lug 26 is disposed a spring30, embracing the bolt 27.,

.hlch is held from displacement within thelug 26 in any approved manner,as by a nut 31. i

. Between the guide 12 and the spring 22 is arranged a late 32,extending laterally upon each side 0 and embracing the portion 20 of thedraw-bar and to the ends of which are se res ectively,"thr0ugh thebrackets 13 and 13 an provided at their forward ends, respec tively',with heads and 36 normally in contact with the shoulders 15 and 16 andwith s ring 37 and 38 between the said heads and t eir associatedbrackets. The bars 33 and 34 are longitudinally movablethrou h the plate32 and the forward movements't ereof are limited by means of nuts 39 and40 upon What we claim is' 1. In a draft ap liance, brackets; mountedupon'the sills 0i tl fe car and spaced a art, a crossiece extendintransversely of t e car, a gui e carried rigi y upon the cross-piece, adraw-bar disposed between the brackets and extending through and to movelongitudinally in the guide and provided with a shoulder forwardly ofthe guide and with a collar rearwardly of the ide; rings interosedbetween the sho der'an guide and etween disposed between the bracketsand positioned to en port the bar.

j 2. In; a aft appliance, spaced brackets head 28, disposed to contactwith a plate 29,

collar and guide, and a roller.

cured bars 33 and 34, extending forwardly,

the said bars and rearward of the said plate.

secured tothe beam of the car, a cross-piece rigidly secured to the beamof the car rearwardly of the brackets, a guide rigidly secured to thecross-piece between the said crosspiece and brackets, a draw-bardisposed between the brackcts and extending through the guide andprovided with a shoulder, a buffer-spring"disposed between the guide andthe shoulder, a collar secured upon the rearward end-of the draw-bar, adraw-spring disposed between the collar and the guide, a bracket rigidlyupstanding from the draw bar and spaced from the sill of the car, and adrawspring disposed between the bracket and the sill.

3. Ina draft appliance, a bracket secured to the sill of the car andspaced. apart, a cross-pieceseoured to the sill of the car and extendingtransversely thereof, a guide ligidly secured to and extending forwardlyof the chesspiece and between the said cross: piece and the brackets, adraw-bar disposed between the brackets and extending through the guideand provided with a shoulder, a roller disposed between the brackets andarranged to support the draw-bar, a bufl'erspring interposed between theshoulder of the draw-bar and the guide, a collar secured upon therearward end of the draw-bar, a

draw-spring interposed between the collar in from the draw-bar andspaced from the sil of the car, a rod mounted to reciprocate in the saidbracket and provided with a buffer-head upon its forward end positionedto contact with the sill, and a spring interosed between the buffer-headand the racket. v

In testimony whereof we affix our signatures in presence of twowitnesses.
